configuration. You need to explicitly configure the build with
@code{--enable-libmp3lame}.
@subsection Option Mapping
@subsection Options
The following options are supported by the libmp3lame wrapper,
the LAME-equivalent options follow the FFmpeg ones.
The following options are supported by the libmp3lame wrapper. The
@command{lame}-equivalent of the options are listed in parentheses.
@multitable @columnfractions .2 .2
@item FFmpeg @tab LAME
@item b @tab b
Set bitrate expressed in bits/s, LAME @code{bitrate} is expressed in
kilobits/s.
@item q @tab V
Set quality setting for VBR.
@item compression_level @tab q
Set algorithm quality. Valid arguments are integers in the 0-9 range.
@item reservoir @tab N.A.
Enable use of bit reservoir. LAME has this enabled by default.
@item joint_stereo @tab -m j
@table @option
@item b (@emph{-b})
Set bitrate expressed in bits/s for CBR. LAME @code{bitrate} is
expressed in kilobits/s.
@item q (@emph{-V})
Set constant quality setting for VBR. This option is valid only
using the @command{ffmpeg} command-line tool. For library interface
users, use @option{global_quality}.
@item compression_level (@emph{-q})
Set algorithm quality. Valid arguments are integers in the 0-9 range,
with 0 meaning highest quality but slowest, and 9 meaning fastest
while producing the worst quality.
@item reservoir
Enable use of bit reservoir when set to 1. Default value is 1. LAME
has this enabled by default, but can be overriden by use
@option{--nores} option.
@item joint_stereo (@emph{-m j})
Enable the encoder to use (on a frame by frame basis) either L/R
stereo or mid/side stereo.
@end multitable
stereo or mid/side stereo. Default value is 1.
